HOLDING iDEVICE FOR RESETTING' SCRAPERS.

Specification of Letters Patent.

Application filedMay 12, 1910. .Seria1"No.580,973.

To all whom it may concern:

'Be it known that I, JOSEPH BENJAMIN CATHY, a citizen of the'UnitedStates, and a resident of Godfrey, in the county of Morgan and State ofGeorgia, have invented a new'and Improved Holding Device for ResettingScrapers, of which the following} is a full, clear,-and exactdescription.

My invention relates to holding devices for resetting scrapers, and ithas for its object to provide one which may be manufactured at littlecost, so that all farmers and; blacksmithsmayprocure, at littleexpense,i means for shapingand resetting, scrapers: after they have beensharpened. When the scrapers are sharpened, after they become; dull,they are usually so out of shape that! they are of verylittle valueuntil they are v reset. While the subject of this application has: beenespecially devised-for resettingscraprs used in cultivating cottonfields, it will be understood that the resetting devices may be used forotherforms, of scrapers. 'Still other objects of the invention willappear in the following complete descrip- In this specification I willdescribe thel preferred 'form of my invention, it being;

Reference is to be had to the accompany-- ing drawlngs'forming a part ofthis specifi-l cation, 1n whlch snnllar characters of ref-..

erence indicate corresponding parts in all the views, and in whichFigure 1 is a side elevation of the inven-; tion; Fig. 2 is a side,sectional elevation ofj the invention; Fig. 3 is an end view of the,

invention;'Fig. 4: is a sectional view on the line 44 of Fig. 2; Fig. 5is a sectional view on the line 55 of-Fig. 2; Fig. 6 is a frag-l showingthe shaping platestFig. 7 is a perspective view of the clamping rod; andFig,

8 is aperspectiveview showing one -of the scrapers, to reset which mydevice has beent devised. 1

By referring to thedrawings, it will be seen that the base member 6 hastransverse; supports 7 a frame being mounted onthe base member 6, andconsisting of a horizon tal member 8 and legs 9 and 10, which aresecured to the basemember '6 and which;

support the said horizontal member, two

pairs of the legs 9 being'disposed at one end of the horizontal member 8and. onefpair of the legs 10 being disposed at the other end of thehorizontal member 8. The inner pair of legs 9 has'lugs 11,.to whichis,pivote'd a lever 12, the lever 12 having the terminal of one of itsarms '13 disposed at substantially right an'gles todts other arm 14.Aroma member 15 is secured to the base memberG .at a centraLportion, thesaid 'foot member being bent at each sideof its central portion, so thatits sides are disposed upwardly,

.parallel to each other, the sides being disposed one at each side ofthe horizontal member 8 and being disposed forwardly, and being securedthereto at 16, as shown in the drawings. The lowerportion of the footmember is disposed forwardly and downwardly tothepoint where it issecured to the base member. Pivoted to-theterminal of the arm 14$ of thelever 12, is a clamping rod 117, the clamping rod 17 being disposedrearwardly between the sides of the ,foot member 15, the rear terminalof the clamp- ,ing rod 17 being shaped into a depending .flange 18,which is disposed at an acute angle relativelyto the body "of theclamping rod. The forward side of this depending flange 18 isprovidedwith a lug19. To the base member 6 are secured two clamping plates 20,these clampmgplatesbeing also d1sposed at an angle to each other, theapex of which is disposedlin the direction of the legs 9. The dependingflange 18 is adapted .to move between-these clamping plates 20.Connecting the terminal. of'the arm 13 of the lever 12 with the clampingrod 17 there is a lifting rod 21, so that when the arm l3 is movedupwardly, it will raise the clamping rod17. A p

The base of'the foot member 15 is 'disposed in a position correspondingwith -a similar part in a scraping machine to which the scraper. platesare normally secured and, when the resetting device is in use, thescraper 22 is disposed immediately behind this foot member, with. thelug 19 of the depending fiange 18: disposed, from the rear, "through theopening 23 in the scraper 22.

The arm 13 of the lever 12 is raised when the'scraper 22 is placedinposition behind the base of'the foot'mem'ber 15,and;when the arm 13 ismoveddownwardly, itdraws the clamping rod 17 forwardly, thereby forcingthesc-raper 22 against'tlie base of the foot member 15, the scraperresting on the base member 6 or being disposed. in close proximitythereto. To secure the best results, the scraper 22 is heated before 1tis placed in position between the foot member 15 and the dependingflange 18 of the clamping rod 17 and while it is still hot and held inposition against the base of the foot member 15, the sides of thescraper 22 are hammered down and rearwardly against the shaping plates20 until they lie fiat against the said shaping plates. As will be seenby referring to the drawings, these shaping plates not only are disposedat angles to each other, but they are inclined rearw'ardly and upwardly,so that when the sides of the scraper 22 are hammered flat against thesaid plates, the scraper will be reset to its normal position, therebypermitting of the attainment of the best results when the scraper isagain mounted on the machine and is in use.

To free the scraper 22 from my device, the arm 13 of the lever 12 israised, which raises the clamping rod 17 and moves it slightlyrearwardly, by which means the scraper 22 is disengaged therefrom.

I prefer to construct the horizontal member 8, the base member 6 and thetransverse member 7 of wood and the other parts of my device of metal,and I also prefer to bolt the parts together as shown in the drawings,but it will be understood that these features are not material to myinvention, as the parts of the device may be constructed of any suitablematerial and may be secured together in any firm manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
